@@raoulschaupp4727 Since the biggest component is the rule book, I'd say A4 surface (210 x 297 mm), with 70mm height. That way the card decks for the different scenarios have their own place under the manual/intro/books. Easiest to setup and organize for now. (Ideally I would print the text in twice the font size on a5 (148.5 x 210 mm), which would make the book thicker, and stacked decks, so the height would be more like 100mm)
